TOWING RECOMMENDATIONS
RECOMMENDED TOWING EQUIPMENT
To avoid damage to bumper fascia and air dams use
of a wheel lift or flat bed towing device (Fig. 3) is
recommended. When using a wheel lift towing device,
be sure the rear end of disabled vehicle has at least
100 mm (4 in.) ground clearance. If minimum ground
clearance cannot be reached, use a towing dolly. If a
flat bed device is used, the approach angle should not
exceed 15 degrees.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the opposite end of the vehicle, especially when towing over
rough terrain or steep rises in the road. If necessary,
remove the wheels from the lifted end of the vehicle
and lower the vehicle closer to the ground, to increase
the ground clearance at the opposite end of the vehicle. Install lug nuts on wheel attaching studs to
retain braking discs.
SAFETY PRECAUTIONS
The following safety precautions must be considered
when preparing for and during a vehicle towing operation:
• Do NOT tow vehicle with front wheels on the
ground. The transaxle can be damaged.
• Secure loose and protruding parts from a disabled
vehicle.
• Always use a safety chain system that is independent of the lifting and towing equipment.
• Do not allow any of the towing equipment to contact the fuel tank of the vehicle being towed.
• Do not go under the vehicle while it is lifted by the
towing equipment.
• Do not allow passengers to ride in a vehicle being
towed.
• Always observe all state and local laws pertaining
to warning signals, night illumination, speed, etc.
• Do not attempt a towing operation that could jeopardize the operator, bystanders or other motorists.
• Do not exceed a towing speed of 48 km/h (30mph).
• Avoid towing distances of more than 24 km (15
miles), whenever possible.
• Never attach tow chains or a tow sling to the
bumper, steering linkage, or constant velocity joints.
TIE DOWN LOCATIONS FOR FLAT BED

Page 11
0 - 10LUBRICATION AND MAINTENANCE
The engine cooling system will develop internal
pressure of 97 to 123 kPa (14 to 18 psi) at normal
operating temperature. Allow the vehicle approximately one half hour to cool off before opening the
cooling system. As an indicator of pressure, squeeze
the upper radiator hose between index finger and
thumb. If it collapses with little effort the system
would have low internal pressure and should be safe
to open to the first safety notch of the coolant pressure bottle cap. Refer to Group 7, Cooling System.
COOLING SYSTEM INSPECTION
Coolant level (Fig. 5) should be inspected when
other engine compartment service is performed or
when coolant leak is suspected. Coolant pressure
bottle level should be inspected when the engine is
cold. The COLD FILL LEVEL mark is located on the
side of the coolant pressure bottle. Cooling system
freeze protection should be tested at the onset of the
winter season or every 12 months. Service is required
if coolant is low, contaminated, rusty or freeze protection is inadequate. To properly test cooling system,
see Group 7, Cooling System.

this group.
SELECTING ANTIFREEZE
ChryslerCorporationrecommendsMopar
Antifreeze/Summer Coolant, or equivalent be used to
winterize and protect cooling system.
PRESSURE CAP
The pressure cap must be secure for the engine
cooling system to perform properly. Inspect and test
pressure cap when cooling system service is performed or when a problem is suspected.
COOLING SYSTEM SERVICE
The cooling system should be drained, flushed and
filled with the proper coolant mixture at the intervals
described in the Lubrication and Maintenance Schedules. Refer to General Information section of this
group. For proper service instructions see Group 7,
Cooling System.
Fig. 5 Coolant Pressure Bottle
The cooling system factory fill is a mixture of 50%
Glycol base antifreeze with silicate inhibitor and 50%
water. Using a suitable hydrometer, measure antifreeze concentration in the coolant pressure bottle
when the engine is cool. If the cooling system has
recently been serviced, allow coolant to circulate for
at least 20 minutes before taking hydrometer reading.
Properly mixed coolant will protect the cooling system
to -37°C (-35°F). If the freeze protection is above
-28°C (-20°F), drain enough coolant from the cooling
system to allow room to add antifreeze to achieve
ENGINE AIR CLEANER
The engine air cleaner should be serviced at the
intervals described in the Lubrication and Maintenance Schedules. Refer to General Information section of this group. Additional information can be
found in Group 14, Fuel System and Group 25, Emission System. Inspect all air cleaner hoses or tubes for
damage or leaks when other engine compartment service is performed. Replace faulty components.

change. Service PCV system if engine oil is discharged into air cleaner.
PCV SYSTEM TEST
Refer to group 25, Emission Control System for
proper procedures to test PCV system.
Fig. 8 PCV System—3.3L Engine
Fig. 6 Air Cleaner
Fig. 7 Cleaning Air Filter Element
CRANKCASE VENTILATION SYSTEM
Engine crankcase pressure and emissions are
vented into combustion chambers through the positive crankcase ventilation (PCV) system (Fig. 8 or 9).
The PCV system should have enough volume to overcome crankcase pressure created by piston backwash.
If a PCV system becomes plugged, the crankcase
pressure will increase and force engine oil past the
piston rings creating oil consumption. Blockage of
PCV system can occur at the vacuum source coupling,
PCV valve or a collapsed hose.
Chrysler Corporation recommends that a PCV valve
not be cleaned. A new Mopar or equivalent PCV valve
should be installed when servicing is required. Over a
period of time, depending on the environment where
vehicle is used, deposits build up in the PCV vacuum

FUEL RECOMMENDATIONS
Chrysler Corporation recommends that only fuel
purchased from a reputable retailer be used. Use high
quality, unleaded gasoline to provide satisfactory
driveability and highest fuel economy. Gasoline containing detergent and corrosion control additives are
desireable. If the engine develops spark knock (audible ping), poor performance, hard starting or stalling, purchase fuel from another source. Engine performance can vary when using different brands of
gasoline with the same octane rating. Occasional light
engine spark knock under heavy acceleration, at low
speed or when vehicle is heavily loaded is not harmful. Extended periods of spark knock under moderate
accelerationoratcruisingspeedcandam-

age the engine. The cause of excessive spark knock
condition must be diagnosed and corrected. For diagnostic proedures refer to Group 14, Fuel System and
Powertrain Diagnostic Procedures manual.
3.3 L ENGINES
Use only unleaded gasoline having a minimum oc-
tane rating of 87.
3.5 L ENGINES
Use of mid-grade unleaded fuel with minimum octane rating of 89 is recommended. Regular unleaded
gasoline having a minimum octane rating of 87 can be
used. Regular fuel can reduce engine performance
and fuel mileage. Premium unleaded gasoline having
a minimum octane rating of 91 can be used if desired.
Refer to Group, 14 for additional information.
FLEXIBLE FUEL ENGINES
CAUTION: Do not use 100% methanol, damage to
fuel system can result.
Use unleaded regular gasoline having a minimum
octane rating of 87 (R=M)/2 and M85 fuel that is 85%
methanol and 15% unleaded gasoline, or a mixture of
these two.
SELECTING GASOLINE
CAUTION: Do not use fuel containing METHANOL
(methyl or wood alcohol) in non-flexible fuel engines, damage to fuel system will result.
Do not use leaded gasoline, damage to catalytic
converter will result and vehicle will not conform to
emission control standards.
ETHANOL, MTBE OR ETBE BLENDS
All Chrysler Corporation vehicles are designed to
use unleaded gasoline ONLY. Gasohol blends, containing 10% Ethanol (ethyl or grain alcohol) 90%
unleaded gasoline can be used provided it has adequate octane rating.
Fuel blends containing up to 15% MTBE (Methyl
Tertiary Butyl Ether) and 85% unleaded gasoline can
be used. Fuel blends containing up to 17% ETBE
(Ethyl Tertiary Butyl Ether) and 83% unleaded gasoline can also be used.
Fuel blended with ethanol, MTBE or ETBE are also
referred to as reformulated or clean air gasoline.
These fuels contribute less emissions to the atmosphere.ChryslerCorporationrecommendsthat
blended fuels be used when available.
nents will result. Methanol induced problems are not
the responsibility of Chrysler Corporation and may
not be covered by the vehicle warranty.

AUTOMATIC TRANSAXLE
The automatic transaxle should be inspected for
fluid leaks and proper fluid level when other under
hood service is performed.
CAUTION: To minimize fluid contamination, verify
that dipstick is seated in the fill tube after fluid level
reading is taken.
TO INSPECT THE TRANSAXLE FLUID LEVEL:
(1) Position the vehicle on a level surface.
(2) Start engine and allow to idle in PARK for at
least 60 seconds. The warmer the transaxle fluid, the
more accurate the reading.
(3) While sitting in driver seat, apply brakes and
place gear selector in each position. Return gear selector to park.
(4) Raise hood and remove transaxle fluid level
indicator (dipstick) and wipe clean with a suitable
cloth.
(5) Install dipstick and verify it is seated in fill
tube (Fig. 1).
CAUTION: Do not overfill automatic transaxle, fluid
leak or damage can result.
(6) Remove dipstick, with handle above tip, take
fluid level reading (Fig. 2). If the vehicle has been
driven for at least 15 minutes before inspecting fluid
level, transaxle can be considered hot and reading
should be above the WARM mark. If vehicle has run
for less than 15 minutes and more than 60 seconds
transaxle can be considered warm and reading should
be above ADD mark. Add fluid only if level is below
ADD mark on dipstick when transaxle is warm.
The automatic transaxle does not require periodic
maintenance when used for general transportation. If
the vehicle is subjected to severe service conditions,
the automatic transaxlewill requirefluid/filter
change and band adjustments every 24 000 km
(15,000 miles). For additional information, refer to
Severe Service paragraph and Lubrication and Maintenance Schedules in General Information section of
this group. The fluid and filter should be changed
when water contamination is suspected. If fluid has
foamy or milky appearance, it is probably contaminated. If the fluid appears brown or dark and a foul
odor is apparent, the fluid is burned, transaxle requires maintenance or service. A circular magnet located in the transaxle pan, collects metallic particles
circulating in the oil. For proper diagnostic and service procedures, refer to Group 21, Automatic Transaxle.

GENERAL INFORMATION
Throughout this group, references may be made to
a particular L.H. platform vehicle by letter or number
designation. A chart showing the breakdown of these
designations is included in the Introduction section at
the front of this Service Manual.
The L.H. platform vehicles have a MacPherson gas
pressurized strut front suspension design (Fig. 1).
The MacPherson strut shock absorber assembly includes the following components. A rubber isolated
top mount, seat and bearing assembly and a coil
spring insulator. The MacPherson strut assembly is
attached to the vehicle at the shock tower using 3
studs which are part of the isolated top mount. The
lower end of the MacPherson strut assembly is attached to the upper leg of the steering knuckle. Attachment of the MacPherson strut assembly to the
steering knuckle is by 2 serrated bolts. A forged lower

control arm assembly (Fig. 1) is attached to the front
cradle and steering knuckle. A tension strut (Fig. 1)
connects the lower control arm assembly to the front
cradle.
A sealed for life front hub and bearing assembly is
attached to the front steering knuckle. The outer C/V
joint assembly is splined to the front hub and bearing
assembly and is retained by a prevailing torque nut.
CAUTION:ONLYFRAMECONTACTHOISTING
EQUIPMENT CAN BE USED ON L.H. PLATFORM VEHICLES. The L.H. platform vehicles have a fully independent rear suspension. The L.H. platform vehicles can not be hoisted using equipment designed
to lift a vehicle by the rear axle. If this type of
hoisting equipment is used damage to rear suspension components will occur.

FRONT SUSPENSION
FRONT SUSPENSION MAJOR COMPONENTS
(FIG. 2)
STRUT ASSEMBLY
The front strut and suspension of the vehicle is
supported by coil springs positioned around the
struts. The springs are contained between an upper
seat, located just below the top strut mount assembly
(Fig. 2) and a lower spring seat on the strut lower
housing.
The top of each strut assembly is bolted to the
upper fender reinforcement (shock tower) through a
rubber isolated mount.
The bottom of the strut assembly attaches to the
top of the steering knuckle with two serrated
through bolts and prevailing torque nuts. Caster is a
fixed setting (net build) on all vehicles and is not
adjustable.
STEERING KNUCKLE
The steering knuckle (Fig. 2) is a single casting
with legs machined for attachment to the front strut
assembly and lower control arm ball joint. The steering knuckle also has machined abutments on the
casting to support and align the front brake caliper
assembly. The knuckle also holds the front drive
shaft outer C/V joint hub and bearing assembly. The
hub is positioned through the bearing and knuckle,
with the constant velocity stub shaft splined through
the hub. The outer C/V joint is retained to the hub
and bearing assembly using a prevailing torque nut.
LOWER CONTROL ARM
The lower control arm (Fig. 2) is a steel forging
with 2 rubber bushings isolating the lower control
arm from the front cradle assembly. The isolator
bushings consist of a metal encased pivot bushing
and a solid rubber tension strut bushing. The lower
control arm is bolted to the cradle assembly using a
pivot bolt through the center of the rubber pivot
bushing and at the tension strut isolator bushing
(Fig. 2).
The ball joint is an integral part of the control arm
and has a non-tapered stud with a notch for clamp
bolt clearance. The stud is clamped and locked into
the steering knuckle leg with a clamp bolt. The ball
joint used on the L.H. Platform vehicle is nonserviceable and if defective must be serviced as part
of the lower control arm.
DRIVESHAFTS
A left and right driveshaft is attached inboard to
the transaxle differential output (or stub) shaft, and
outboard to the driven wheel hub and bearing assembly.
To deliver driving force from the transaxle to the
front wheels during turning maneuvers and suspension movement. Both shafts are constructed with constant velocity universal joints at both ends.
Both shafts have a Tripod (sliding) joint at the
transaxle end and C/V joints (with splined stub
shafts) on the hub ends. Due to the transaxle location the connecting shafts between the C/V joints are
of different length and construction. The left shaft is
longer than the right. Both the left and right drive
shafts are of the solid bar type. No tubular drive
shafts are used on any available L.H. platform vehicle and powertrain combinations.
TENSION STRUTS
The L.H. platform vehicle uses a tension strut (Fig.
2) on each side of the vehicles front suspension. The
tension strut controls longitudinal (for-and-aft) movement of the front wheels of the vehicles. Controlling
the longitudinal movement of the wheels reduces
harshness when wheels hit sudden irregularities in
the road surface.
STABILIZER BAR (SWAY BAR)
The stabilizer bar (Fig. 2) interconnects the front
strut assemblies of the vehicle. The purpose of a
stabilizer bar is to control the body roll of the vehicle.
STABILIZER BAR LINK ASSEMBLY
The stabilizer bar link assembly (Fig. 2) is used to
attach the stabilizer bar to the front strut assemblies.
This reduces the fore-and-aft rate of the sway bar
from the rest of the suspension.

Wheel Alignment Service Procedure............7
The method of checking front alignment will vary
depending on the type of equipment being used. The
instructions furnished by the manufacturer of the
equipment should always be followed. With the exception that the alignment specifications recommended
by Chrysler Corporation be used.
There are six basic factors which are the foundation
to front wheel alignment. These are vehicle height,
caster, camber, toe-in, steering axis inclination and
toe-out on turns. Of the six basic factors only TOE
IN is mechanically adjustable on the L.H. platform vehicle (Fig. 1).
CAUTION: Do not attempt to modify any suspension
or steering components by heating or bending of
the component.
Wheel alignment adjustments can only be
made for the Toe In setting on the L.H. platform
vehicles.
Toe is measured in degrees or inches and is the
distance the front edges of the tires are closer (or
farther apart) than the rear edges. See Front Wheel
Drive Specifications for Toe settings.
PRE-ALIGNMENT
Before any attempt is made to change or correct
front wheel alignment. The following inspection and
necessary corrections must be made on those parts
which influence the steering of the vehicle.
(1) Check and inflate tires to recommended pressure. All tires should be the same size and in good
condition and have approximately the same wear.
Note type of tread wear which will aid in diagnosing,
see Wheels and Tires, Group 22.
(2) Check front wheel and tire assembly for radial
runout.
(3) Inspect lower ball joints and all steering linkage
for looseness.
(4) Check for broken or front and rear springs.
Alignment must only be checked after the vehicle
has had the following checked or adjusted. Tires set
Page 26
to recommended pressures, full tank of fuel, no passenger or luggage compartment load and is on a level
floor or alignment rack.
Just prior to each alignment reading. The vehicle
should be bounced (rear first, then front) by grasping
bumper at center and jouncing each end an equal
number of times. Always release bumpers at bottom
of down cycle.

GENERAL INFORMATION
All L.H. platform vehicles are equipped with an unequal length drive shaft system (Fig. 1). The left side of
the vehicle is equipped with a longer drive shaft than
the right side of the vehicle. The L.H. platform uses solid
interconnecting shafts on both sides of the vehicle.
The driveshaft assemblies are three piece units.
Each driveshaft has a Tripod Joint, an Interconnecting Shaft and a outer C/V joint. The Tripod Joint is
splined onto the transaxle stub shaft, and the outer
C/V joint has a stub shaft that is splined into the
front wheel hub and bearing assembly.
Outer C/V Joint Sealing Boot Service.......... 50
Service Procedures....................... 42
Servicing Driveshafts...................... 42
The inner tripod joint boots, on the L.H. platform vehicle are of different materials. The left
inner boot is made of high temperature application silicone, and the right inner boot is made of
hytrel plastic. When drive shaft boots are replaced be sure boots of the correct material are
used on the correct side of the vehicle.
The driveshafts used on the L.H. platform vehicles
are supplied by Saginaw Division for all available
drivelines.

SERVICE PROCEDURES
Procedures for removal and installation of driveshafts on the L.H. platform vehicles are different and
somewhat easier, then those on other front wheel
drive vehicles. This new drive shaft design, allows
both drive shafts to be removed from the vehicle
without dismantling the transaxle.
CAUTION: Boot sealing is vital to retain special lubricants and to prevent foreign contaminants from entering the C/V joint. Mishandling, such as allowing the
assemblies to dangle unsupported, pulling or pushing
the ends can cut boots or damage C/V joints. The L.H.
platform driveshafts use no retention system to retain
the spider assembly in the tripod housing. During removal and installation procedures always support both
ends of the driveshaft to prevent damage or disengaging tripod joint. Therefore, do not pull on the interconnecting shaft when attempting to remove drive shafts
from vehicle.

GENERAL INFORMATION
The rear suspension used on the L.H. platform is a
fully independent rear suspension. The suspension
utilizes a MacPherson strut assembly at each rear
wheel of the vehicle.
CAUTION: Only frame contact hoisting equipment
can be used on L.H. platform vehicles. The L.H.
platform vehicles have a fully independent rear suspension. The L.H. platform vehicles can not be
hoisted using equipment designed to lift a vehicle
by the rear axle. If this type of hoisting equipment is
used damage to rear suspension components will
occur.
A forged rear spindle bolts to each rear strut assembly. The movement of the rear spindle is controlled laterally using lateral links going from the
front and rear of the spindle to the rear cross member. Fore and aft movement of the spindle is controlled by a trailing arm.
Rear Wheel Toe Setting Procedure............ 55
Servicing Lateral Links..................... 69
Servicing Rear Struts...................... 55
Suspension Coil Springs................... 61
The lateral links and trailing arm have rubber isolator bushings at each end. The lateral links are
attached to the rear crossmember and spindle, using
a common bolt and nut assembly at each end. The
trailing arm bolts to the bottom of the spindle and to
a bracket attached to the floor pan of the vehicle.
Lateral links, trailing arms and spindles are normally replaced only when the part has been damaged
or when the vehicle has been involved in an accident.
If a suspension part has been damaged, be sure to
check the underbody dimensions of the car. If the
underbody dimensions are not correct, the frame of
the vehicle must be straightened, before replacement
suspension components are installed.
Note: If a rear suspension component becomes
bent, damaged or fails, no attempt should be
made to straighten or repair it. Always replace
with a new component.
Rear Wheel alignment adjustments can only
be made for the Toe In setting on the L.H. platform vehicles.
Toe is measured in degrees or inches and is the
distance the front edges of the tires are closer (or
farther apart) than the rear edges. See Front Wheel
Drive Specifications for Toe settings.
REAR WHEEL TOE ADJUSTMENT
(1) Prepare vehicleas describedin the PreAlignment procedure.
(2) Loosen lateral link, adjustment link jamnuts
(Fig. 1). Rotate adjustment links as required to set
rear wheel Toe to specifications. Do not exceed the
maximum length dimensions of the lateral links
shown in (Fig. 2). Both dimensions must be
checked to ensure they do not exceed maximums allowed.

Fig. 2 Lateral Link Maximum Length Dimensions
(2) Remove the rear wheel and tire assembly from
the vehicle.
(3) If vehicle is equipped with rear disc brakes,
remove the rear caliper assembly from the adapter.
Refer to Rear Disk Brakes in Group 5 Brakes of this
Service manual for required caliper removal procedure. After removing caliper assembly store caliper by
hanging it from vehicle (Fig. 1). Do not let rear caliper assembly hang from flexible brake hose. If vehicle
is equipped with rear drum brakes, remove the brake
flex hose bracket from the support plate and wheel
cylinder (Fig. 2).
Fig. 1 Rear Wheel Toe Adjustment At Lateral Links
CAUTION:
The maximum lengths of the adjustable lateral link
at the locations shown in (Fig. 2) must not be
exceeded. If these maximum lengths are exceeded,
inadequate retention of adjustment link to the inner
and outer link may result. Ensure that the adjustment sleeve jam nuts are torqued to the required
specifications when the Toe setting procedure is
completed.

REAR CROSSMEMBER
The L.H. platform vehicles are available with two
different rear crossmembers depending on the suspension package the vehicle was built with. The
crossmembers visually look the same between the
standard and performance suspension packages, but
the mounting location for the lateral links is different. The performance suspension crossmember is
identified by a identification hole in the crossmember (Fig. 1). The performance crossmember identification hole is located on left side of crossmember on
the rear vertical wall. If crossmember is replaced
be sure the correct crossmember is installed or
handling of the vehicle will be adversely affected.

GENERAL INFORMATION
Throughout this group, references may be made to
a particular L.H. platform vehicle by letter or number
designation. A chart showing the break down of these
designations is included in the Introduction Section
at the front of this service manual.
The L.H. platform vehicles are available with 4
different types of brake systems. The standard brake
system consists of front disc brakes and rear drum
brakes which are not available with Anti-Lock. The
second optional brake system is 4 wheel disc brakes
without Anti-Lock. The third optional brake system is
Anti-Lock brakes, which is only available with front
and rear disc brakes. The fourth optional brake system is 4 wheel disc brakes with traction control. The
traction control system is dependent on the Anti-Lock
system and is not available without Anti-Lock.
Standard brake equipment consists of:
• Double pin floating caliper front disc brakes.
• Rear automatic adjusting drum brakes.
• Proportioning valve on non Anti-Lock brakes.
• Master cylinder.
• Vacuum power booster.
• Double pin floating caliper rear disc brakes are
available on some models and standard with AntiLock.
The Anti-Lock braking system, uses the standard
power brake system caliper assemblies, braking
discs, pedal assembly, brake lines and hoses. The
unique parts of the Anti-Lock braking system consists of the following components. Unique proportioning valves, wheel speed sensors, tone wheels,
electronic control unit, hydraulic control unit and
the conventional master cylinder and power booster.

WHEEL CYLINDERS..................... 20
These components will be described in detail in the
Anti-Lock brake section in this group of the service
manual.
The front disc brake shoes have non-asbestos semi-
metallic linings.
The hydraulic brake system (Fig. 1 2 and 3) is
diagonally split on both the Non-ABS and ABS braking system. With the left front and right rear brakes
on one hydraulic system and the right front and left
rear on the other.
Fig. 1 Diagonally Split Braking System
(Typical Non-ABS System)
All available brake systems on the L.H. platform
vehicles, except rear drum brakes use the same type
of brake line fittings and tubing flares. The brake line
and fittings used is double wall tubing with ISO
style tubing flares and fittings at all tubing joint
locations. See (Figs. 2 and 3) for specific joint locations and tube fitting size.
Vehicles equipped with rear drum brakes. Use conventional double inverted style flares at the brake
flex hose to wheel cylinder connections.
Avoid scuffing the brake tubes when servicing.
Scuffing the brake tubes will scrape off the anticorrosion coating on the brake tubes.
CAUTION: At no time when servicing a vehicle, can
a sheet metal screw, bolt or other metal fastener be
installed in the shock tower to take the place of an
original plastic clip. Also, NO holes can be drilled
into the front shock tower in the area shown in (Fig.
4), for the installation of any metal fasteners into the
shock tower.
Because of the minimum clearance in this area
(Fig.4) installation of metal fasteners could damage
the coil spring coating and lead to a corrosion failure of the spring. If a plastic clip is missing, or is
lost or broken during servicing a vehicle, replace
only with the equivalent part listed in the Mopar
parts catalog.
The L.H. platform front disc brakes, use a double
pin, single piston floating caliper design supplied by
Kelsey-Hayes. The front disc brake caliper assembly
mounts directly to rails on the steering knuckle and
is secured to the steering knuckle using 2 bolts.
CAUTION: Caliper pistons, boots and seals for the
different caliper assemblies used on the front and
rear disc brake assemblies are not interchangeable.
Misusage could result in a complete brake system
failure. Be sure that the parts are replaced with the
correct replacement parts, refer to the parts book
for the type and model year of the vehicle being
worked on.
The master cylinder is anodized, lightweight aluminum, with a bore size of 23.8mm (15/16 in.).
Check master cylinder reservoir brake fluid level a
minimum of twice a year.
Master cylinder brake fluid reservoirs used on all
L.H. platform vehicles include a brake fluid level
sensor. The brake fluid level sensor location is in the
body of the brake fluid reservoir (Fig. 1). In the event
of low brake fluid level in the brake fluid reservoir,
the RED brake warning light in the instrument panel
will turn on.
Master cylinder assembly, brake fluid reservoirs on
both standard and Anti-Lock brake systems. Are
marked with a MAX fill line indicating the brake
fluid reservoirs proper fluid level (Fig. 1).
When filling brake fluid reservoir, use only
Mopart brake fluid or an equivalent stored in a
tightly sealed container. Brake fluid must conform to DOT 3, specifications.
If necessary, add brake fluid to brake fluid reservoir, bringing brake fluid level to the MAX fill line
shown on fluid reservoir (Fig. 1).
DO NOT use brake fluid with a lower boiling point
then DOT 3, as brake failure could result during
prolonged hard braking.
DO NOT use petroleum-based fluid because seal
damage in the brake system will result.

ADJUSTING REAR SERVICE BRAKES
Normally, self adjusting drum brakes will not
require manual brake shoe adjustment. Although in the event of a brake reline it is advisable to make the initial adjustment manually to
speed up the adjusting time.
(1) Raise the vehicle so all wheels are free to turn.
See Hoisting Recommendations in the Lubrication
And Maintenance Section, at the front of this service
manual.
(2) Remove rear brake adjusting hole rubber plug
(Fig. 1), from the rear brake shoe support plate.
(3) Be sure parking brake lever is fully re-
leased.
(4) Insert a medium blade screwdriver (Fig. 2) or
equivalent through the adjusting hole in support
plate and against star wheel of adjusting screw. Move
Fig. 1 Brake Adjusting Hole Plug
handle of tool downward until a slight drag is felt
when the road wheel is rotated.
(5) Insert a thin screwdriver or piece of welding rod
into brake adjusting hole (Fig. 2). Push adjusting
lever out of engagement with star wheel. Care
should be taken so as not to bend adjusting
lever or distort lever spring. While holding adjust-
ing lever out of engagement with star wheel, back off
star wheel to ensure a free wheel with no brake shoe
drag.
Page 96
Fig. 2 Rear Brake Shoe Adjustment
(6) Repeat above adjustment at the other rear
wheel. Install adjusting hole rubber plugs (Fig. 1) in
rear brake supports.
TESTING APPLICATION ADJUSTER OPERATION
Place the vehicle on a hoist with a helper in the
driver’s seat to apply the brakes. Remove the access
plug from the rear adjustment slot in each brake
support plate (Fig. 1) to provide visual access to brake
adjuster star wheel. Then, to eliminate the possibility
of maximum adjustment, where the adjuster does not
operate because the closest possible adjustment has
been reached. Back the star wheel off approximately
30 notches. It will be necessary to hold the adjuster
lever away from the star wheel to permit this adjustment.
Spin the wheel and brake drum in the forward
direction, and with a greater than normal force apply
the brakes suddenly. This sudden application of force
will cause the leading brake shoe to leave the anchor.
The wrap up effect will move the leading shoe, and
the spring will pull the adjuster lever down. Upon
application of the brake pedal, the lever should move
down, turning the star wheel. Thus, a definite rotation of the adjuster star wheel can be observed if the
automatic adjuster is working properly. If one or more
adjusters do not function properly, the respective
drum must be removed for adjuster servicing.

PRESSURE BLEEDING
Before removing the master cylinder cover, wipe it
clean to prevent dirt and other foreign matter from
dropping into the master cylinder.
CAUTION: Use bleeder tank Special Tool C-3496-B
or equivalent, with Snap-On adapter BB400-9A or
equivalent (Fig. 1 and 2), to pressurize the brake
hydraulic system for bleeding.
Fig. 1 Pressure Bleeding Adapter Mounted On Fluid
Reservoir
BLEEDING BRAKE SYSTEM
CAUTION: For bleeding the L.H. platform Anti-Lock
brakes hydraulic system, see the Anti-Lock Brake
system service procedures in this group of the service manual. It describes in detail the required procedure which needs to be followed when bleeding
the Anti-Lock brake system.
Fig. 2 Pressure Bleeding Vehicle Brake System
Follow pressure bleeder manufacturer’s instructions, for use of pressure bleeding equipment.
When bleeding the brake system. Some air may be
trapped in the brake lines or valves far upstream. As
much as ten feet from the bleeder screw (Fig. 3).
Therefore, it is essential to have a fast flow of a large
Page 97
5 - 6BRAKES
volume of brake fluid when bleeding the brakes. This
will ensure all the air is bled from the brakes hydraulic system.
Fig. 3 Trapped Air in Brake Line
(1) Remove rubber dust caps from all 4 bleeder
screws.
(2) Attach a clear hose to the bleeder screw at one
wheel and feed the hose into a clear jar containing
fresh brake fluid (Fig. 4).
Enough fluid has not passed through the system to
expel all the trapped air. Be sure to monitor the fluid
level in the pressure bleeder. It must stay at the
proper level so air will not be allowed to re-enter the
brake system through the master cylinder.
(6) Replace all 4 bleeder screw rubber dust caps.
BLEEDING WITHOUT A PRESSURE BLEEDER
If a pressure bleeder is not available. A good brake
fluid flow can be obtained by manual bleeding of the
brake hydraulic system, following these steps.
(1) Remove rubber duct caps from all 4 bleeder
screws.
(2) Attach a clear hose to the bleeder screw at one
wheel and feed the hose into a clear jar containing
fresh brake fluid (Fig. 4).
(3) Pump the brake pedal three or four times and
hold it down before the bleeder screw is opened.
(4) Then open the bleeder screw at least 1 full turn.
When the bleeder screw opens the brake pedal will
drop all the way to the floor.
(5) Release the brake pedal only after the bleeder
screw is closed.
(6) Repeat steps 1 through 3, four or five times at
each bleeder screw. This should pass a sufficient
amount of fluid to expel all the trapped air from the
brakes hydraulic system. Be sure to monitor brake
fluid level in master cylinder fluid reservoir, to ensure
it stays at a proper level. This will ensure air does not
re-enter brake hydraulic system through master cylinder.
(7) Only after a short stroke and solid brake pedal
feel is obtained. Test drive vehicle to ensure brakes
are operating correctly and brake pedal is solid.
(8) Replace all 4 bleeder screw dust caps.
Fig. 4 Proper Method for Purging Air From Brake
System (Typical)
CAUTION: Just cracking the bleeder screw often
restricts fluid flow, and a slow, weak fluid discharge
will NOT get all the air out.
(3) Open bleeder screw (Fig. 4) on caliper assembly
or wheel cylinder, at least one full turn or more to
obtain an adequate flow of brake fluid.
(4) After 4 to 8 ounces of brake fluid has been bled
through an individual wheel’s brake hydraulic system. And an air-free flow (no bubbles) is maintained
in the clear plastic hose and jar, this will indicate a
good bleed of this individual hydraulic circuit.
(5) Repeat the procedure at all the other remaining
bleeder screws. Then check the pedal for travel. If
pedal travel is excessive or has not been improved.
TESTING FOR BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or
deteriorated rubber parts.
Swollen rubber parts indicate the presence of a
petroleum based fluid mixed in with the brake fluid.
To test for contamination, put small amount of
drained brake fluid in clear glass jar. If fluid separates into layers, there is petroleum based fluid contamination of the brake fluid.
If contaminated, drain and thoroughly flush system.
Replace master cylinder, proportioning valve, caliper
seals, wheel cylinder seals and all hoses.
ROAD WHEEL STUD NUT TIGHTENING
(1) Install the wheel and tire assembly.
(2) Tighten the wheel mounting stud nuts in proper
sequence (Fig. 5) until all nuts are torqued to half
specification.
(3) Then repeat the tightening sequence to the full
specified torque of 129 Nzm (95 ft. lbs.).
Flexible rubber hose is used at both the front
brakes and rear brakes. Inspection of brake hoses
should be performed whenever the brake system is
serviced and every 7,500 miles or 12 months, whichever comes first (every engine oil change). Inspect
hydraulic brake hoses for severe surface cracking,
scuffing, or worn spots. Should the fabric casing of
the rubber hose be exposed due to cracks or abrasions
in the rubber hose cover, the hose should be replaced
immediately. Eventual deterioration of the hose can
take place with possible burst failure. Faulty installation can cause twisting and wheel, tire or chassis
interference.
The steel brake tubing should be inspected periodically for evidence of physical damage or contact with
moving or hot components.
The L.H. platform vehicles equipped with Anti-Lock
brakes, uses flexible hose to connect the master cylinder to the hydraulic control unit (HCU) (Fig. 1).
These hoses have a flexible stainless steel braid over
the brake hose and tube assemblies. These hoses also
must be inspected as noted above for any signs of

Banjo connector to the caliper assembly. Then attach
the remaining hose end bracket to the vehicle frame
to minimize hose twisting. Then hand start the steel
brake tube fitting into the hose end fitting. Tighten
all attachment screws and tube fittings to specified
torque. The frame bracket is keyed so that it will only
fit one way.
On vehicles equipped with rear drum brakes, first
install rear brake flex hose into wheel cylinder then
attach bracket to brake support plate. Then attach
brake hose end bracket to vehicle frame to minimize
hose twisting. Then hand start the steel brake tube
fitting into the hose end fitting. Tighten all attachment screws and tube fittings to their specified torque
(See Specifications Section) at the end of this group
for the required fitting torques.
Vehicles equipped with rear disc brakes have brake
flex hoses attached to the brake caliper on each side
of vehicle. The brake flex hose should be first attached to the Banjo bolt at the caliper and then
secured the flex hose/bracket at the vehicle frame.
Then attach the steel brake tubing to the hose fitting.
Tighten all attachment screws and brake line tube
fittings to their specified torque (See Specifications
Section) at the end of this group for the required
fitting torques.
INSTALLATION OF BRAKE HOSE
Always use factory recommended brake hose to ensure quality, correct length and superior fatigue life.
Care should be taken to make sure that the tube and
hose mating surfaces are clean and free from nicks
and burrs. Front and rear right and left side
hoses, are not interchangeable.
Connections should be correct and properly made.
Use new copper seal washers on all connections using
Banjo Bolts and tighten all fittings to their specified
torques.
The flexible front hydraulic brake hose should always be installed on the vehicle by first attaching the
REPAIR AND INSTALLATION OF BRAKE
TUBING
Only double wall 4.75mm (3/16 in.) steel tubing
should be used for replacement. L.H. platform
brake tubes are coated with a zinc alloy and
aluminum rich coating referred to as Prokote
2000. If brake line tubing requires replacement, brake line tubing with this same coating
should only be used as a service replacement.
Care should be taken when replacing brake tubing,
to be sure the proper bending and flaring tools and
procedures are used, to avoid kinking. Do not route
the tubes against sharp edges, moving components or

into hot areas. All tubes should be properly attached
with recommended retaining clips.
Care must be taken during the removal and replacement of components on a vehicle equipped with
Anti-Lock brakes. To avoid damage to the flexible
stainless steel hoses between the master cylinder and
Anti-Lock hydraulic control unit.
HYDRAULIC BRAKE LINE TUBING FLARES
All available brake systems used on L.H. platform
vehicles use ONLY ISO STYLE TUBING FLARES(FIG. 2) at all hydraulic tubing to component locations. Except the rear drum brake flex hose to
wheel cylinder connection.
CAUTION: ALWAYS USE THE PROPER TYPE OF ISO
FLARING TOOL AND REQUIREDPROCEDURE,
WHEN TUBE FLARING IS REQUIRED WHEN SERVICING THE VEHICLES HYDRAULIC BRAKE SYSTEM. THIS IS REQUIRED TO ENSURE THE INTEGRITY OF THE VEHICLE’S HYDRAULIC BRAKING
SYSTEM.

TO REPAIR OR FLARE TUBING (I.S.O. STYLE)
Using Tubing Cutter, Special Tool C-3478-A or
equivalent, cut off damaged seat on tubing (Fig. 3).
Ream out any burrs or rough edges showing on inside
of tubing. This will make the ends of tubing square
(Fig. 4) and ensure better seating of flared end tubing. PLACE TUBE NUT ON TUBING BEFORE
FLARING THE TUBING.
ISO TUBING FLARE
CAUTION: All ISO style tubing flares (Fig. 2) are of
metric dimensions. When performing any service
procedures on a vehicle using ISO style tubing
flares, metric size tubing of 4.75 mm MUST be used
with metric ISO tube flaring equipment.
Fig. 4 Brake Tube Preparation For Flaring
To create a (metric) ISO style tubing flare, Use
Snap-On Flaring Tool TFM-428, (Fig. 3) or equivalent. See (Fig. 5) and proceed with the steps listed
below. Be sure to place the tubing nut on tube
before proceeding to flare the tubing.
(1) Carefully prepare the end of the tubing to be
flared. Be sure the end of the tubing to be flared is
square and all burrs on the inside of the tubing are
removed (Fig. 4). This preparation is essential to
obtain the correct form of a (metric) ISO tubing
flare.
(2) Open the jaws of the Flaring Tool. Align the
mating size jaws of the flaring tool around the size of
the tubing to be flared. Close the jaws of the Flaring
Tool around the tubing to keep it from sliding out of
the flaring tool, but do not lock the tubing in place.
See (Fig. 3 and 5)
Page 100
(3) Position tubing in jaws of the Flaring Tool so
that it is flush with top surface of flaring tool bar
assembly. (See Fig. 5).
(4) Install the correct size adaptor for the brake
tubing being flared, on the feed screw of the yoke
assembly. Center the yoke and adapter over the end
of the tubing. Apply lubricant to the adapter area
that contacts brake tubing. Making sure the adapter
pilot is fully inserted in the end of the brake tubing.
Screw in the feed screw of the yoke assembly until
the adaptor has seated squarely on the surface of the
bar assembly (Fig. 5). This process has created the
(metric) ISO tubing flare.
STOP LAMP SWITCH ADJUSTMENT
The stop lamp switch incorporates a self adjusting
feature. If adjustment or replacement is required,
proceed as follows: Install the switch in the retaining
bracket and push the switch forward as far as it will
go. The brake pedal will move forward slightly (Fig.
6). Gently pull back on the brake pedal bringing the
striker back toward the switch until the brake pedal
will go back no further. This will cause the switch to
ratchet backward to the correct position. Very little
movement is required, and no further adjustment is
necessary.
